Hi Marek,

I cannot reproduce the hang or any issues with the game with your patch for
unsafe math on the ML.


Thanks,

Hi sarnex,

Could you please re-enable unsafe math and test if it works with Dota 2 Reborn
now? Mesa master has some fixes which might fix the hang. We need to enable
unsafe math for better performance.

Thanks.

I cannot reproduce this on llvm git, older llvm, or older mesa. Maybe the game
changed.
